I SEMILOOSE-WRAJPPED JBOX.

application filed December 20, 1920. Serial No. 431,912.

To all whom it may concem:

Be it known that I, HARRY BRIDGMAN SMITH, a citizen of the United States, and resident of Brooklyn, in the county of Kings 0 and State of New York, have invented cer tain new and useful Improvements in Semi-- loose-Wrapped Boxes, of which the followinifs a specification.

y invention relates to a distinctly new to type of box which may be called, for descriptive purposes, a semi-loose wrapped box.

Wrapped or covered paper boxes have heretofore been produced in two distinct types, in one of which, usually called in the trade a tight-wrapped box, the covering paper is adhesively secured to the shell material throughout their engaging areas. In the other type, known as a loose-wrapped box, the covering paper is adhesively connected to the shell only along relatively narrow, inturned marginal portions of the cover material, the exposed portions of the cover being unconnected to the shell, and lying more or less loosely thereon, and presenting a distinctly different appearance from the tight-wrapped boxes with their tightly fitting coverings.

An object of the present invention is to produce a new, distinctive and attractive style of box which has some of the characteristics of each of the well-known types, and which appeals to the trade by reason of its novelty of structure and appearance, strength and other structural characteris tics, cheapness, and other considerations.

Another object is to provide a box which may be made by improved methods, with increased output-speed and economy.

Generally described, a box constructed in accordance with my invention comprises a shell, mainly connected to a cover sheet by adhesive contact throughout substantially the entire engaging areas of end portions of the respective parts, and with other p-ortions of the shell and cover material substantially unconnected by adhesive, or connected only along narrow marginal portions of the respective blanks. A box constructed has the cover paper tightly secured to the shell throughout the exposed end surfaces of the box, and loosely overlying the shell at all other exposed surfaces including the body portion (top or bottom of the box part, as the case may be) and sides.

While a box so constructed requires more adhesive than a box of complete loosewrapped construction, it requires considerably less than a tight-wrapped box, and therefore, a considerable saving in cost of glue is accomplished as compared' with boxes of the last-named type, while some of the characteristics of the tight-wrapped box are retained, and also some characteristics of the loose-wrapped type are incorporated, as reviously explained.

oxes of the present sort are well adapted for production by methods of my invention, in which a sheet or blank of shell material is applied to a sheet or blank of covering material with adhesive between them to form an initial assembly, and outwardly extending marginal portions of the cover blank or sheet are then folded over upon and adhesively secured to adjacent margins of the shell, these margins usually being outward portions of the side wings of the respective sheets or blanks, and the initial covered assembly is then bent or folded into complete box form. Such methods are shown in my previous applications Ser. No. 254,630, filed September 18, 1918 and Ser. No. 370,180, filed. March 31, 1920.

In a companion application, executed on even date herewith, I have disclosed a method which is, in some respects, a continuation and improvement upon my previous methods as disclosed in the above mentioned applications, and is particularly suitable for making boxes of the present type.

The characteristics and advantages of my invention are further sufliciently'explained in connection with a detail description of the accompanying drawing, which'shows an exemplifying structure in which the invention is embodied. After considering this embodiment, persons skilled in the art will understand that many modifications may be made within the principles of the invention; and I contemplate the employment of any structures which are properly within the scope of the appended claims.

Fig. 1 is a bottom view of a suitable box shell blank, properly glued.

bl of Fig. ama be shaped into box form.

ig. 4 is a erspective view of a completed box part, eitlier the top or bottom section of a two-part box, embodying my invention.

Fig. 5 is a horizontal section in the 5-5, Fig. 4.

Fig. 6 is a vertical section on the line e-e, Fig. 4.

Fig. 7 is a transverse section on the line 7-7, Fig. 4.

Fig. 1 shows a shell blank S, usually of cardboard of suitable thickness, comprising a body portion 1, side wings 2, end wings 3 and corner laps 4, in this case extending from the ends of the side wings. The blank is severed on the lines 5 to disconnect adjacent portions of the end wings and corner laps, and is scored or creased along the lines 6 to facilitate subsequent bending. On the under surface of the blank as shown in Fig. 1, adhesive is applied to the surfaces of the end wings, and corner laps; and although it is not necessary in all cases to entirely cover these portions of the blank, it is preferable in some cases to entirely cover these surfaces with adhesive, as in the present exemplification of the invention. Other portions of this surface of the blank, namely the body portion 1 and side wings 2, are preferably left entirely free of adhesive, as shown.

Stripes 7 of adhesive are placed along outer margins of the u per surfaces of side wings and adjacent end s of the corner laps, as shown in Fig. 2, and also along upper surface margins 8 of the end wings, and the shell blank is placed flatwise upon a cooperative cover blank C, as shown in Fig. 2, this blank comprising a body portion 10, side wings 11, end wings 12 and corner laps 13, which may desirably be cut away on the diagonal lines 14, although this is not essential. The cover blank also has the side wings formed with projecting margins 15 and the cover end wings have projecting margins 16. The cover side wing margins 15 are now folded over and pressed upon the adhesive stripes 7 of the shell surfaces (one of the cover margins being shown folded over and the other unfolded in Fig. 2) producing a complete box blank assembly. This is now shaped into box form, involving in the present embodiment the steps of separating shell end wings 3 from cover end wings 12. as shown in Fig. 3, whereupon the previously engaged surfaces of these wings are exposed, both plane 1 ,avoees covered with adhesive, the adhesive upon surfaces of the cover end Wings having been placed thereon by previous contact with the shell end wings. The side wings of the assembly are then folded up-as also shown in Fig. 3; the corner laps are folded in shaped over a former or plunger 7 (not.

shown in the drawing) so that the parts may be suitably pressed and secured in position. The projecting margins 16 of the cover end wings are then turned in and down and secured upon adhesive stripes 8 of the shell end wings.

There is thus produced a box structure shown in Fig. 4, in which the exposed end portions, consisting of cover end wings 12, are tightly glued to underlying parts of the box-end structure, and all other exposed portions of the box, consisting of the cover side wings 11 and body portion 10, are entirely free from the underlying shell portions and lie more or less loosely thereon, this freedom being indicated by spaces in sectional Figs. 5, 6 and 7 between the shell and adjacent portions of the cover side wings and body portion, while the tight adhesive engagement of end portions of the structure is indicated in Figs, 5 and 6, by the absence of any space between the cover and shell members respectively. The end portions of the complete box, therefore. present the appearance of a tight-wrapped box and the central (side and body) portions present the appearance of a loosewrapped box. The completed box part is also characterized by the absence of any exposed or raw edges of the shell material, since at every exposed point the shell material is completely enclosed by the cover paper.

The terms side and end, as applied to different wing portions of the blanks and to parts of the completed box, have mainly relatively and not limiting signifi cance, since evidently if the sides are made shorter and the ends are made longer, the present sides of the box will then appear to he ends, and vice versa.

After considering the single embodiment of the invention above described, and especially after also considering my other applications herein mentioned, persons skilled in the art will understand that many variations may be made within the principles of he invention; and I contemplate the ema r/ones ployment at any structures which are rep-- erIJy within the scope of the appended c aims.
